MECHANISM FOR PACKING SLIVERS DISCHARGED FROM CARDING. DRAWING, AND LIKE MACHINES Filed Nov. 20, 1933 3 Sheets-Sheet 3 Federated May 1, 1934 UNITED STATES MECHANISM FOR PACKING SLIVERS DIS- CHARGED FROM CARDING, DRAWING AND LIKE MACHINES Joseph Ryder Bee, Leeds, England Application November 20, 1933, Serial No. 698,812 In Great Britain November 18, 1932 4 Claims.

This invention relates to packing or tramping mechanism for carding, drawing and like machines which are used in the treatment of fibrous substances, and from which the said fibrous substances are delivered. from same in the form of slivers that are to be filled and pressed into cans or receptacles arranged to receive same.

As is well known, the slivers of fibrous substances when discharged from the machine are of such a light and fluffy nature that they have to be pressed or packed down into the can or receptacles in order to enable longer lengths of said slivers to be delivered before the filled cans or receptacles are removed for empty ones to take their places. To attain this object it is usual to have reciprocating packing or pressing members which operate within the receptacles under such conditions that when desired by the attendant or when the receptacles have received the de sired quantity of sliver, a lever is operated and the rising and descending motions of the packing members are thereby arrested while and when the said member is raised to its highest position and clear of the receptacles. My present invention consists in the employment of a known form of cam-operated lever mechanism for imparting the vertically reciprocating movements to the pressing member or members, in combination or conjunction with engaging, disengaging and lock- 30 ing devices whereby the starting of the pressing member into action, the arresting of such action and the positive locking and retaining of the said pressing member in its highest or raised position, are effected and sustained with precision; in this 55 manner avoiding all risk of injury to the attendant and damages incident to the sudden uncontrolled descent of the pressing member that are experienced in connection with other forms of mechanism heretofore proposed or made use of.

In carrying my invention into effect I make use of the devices hereinafter described by reference to the accompanying sheets of drawingsin certain of which two cans or receptacles are used in connection with one and the same machine, one can being arranged to receive the sliver until it is filled, on which the sliver is then directed and delivered into the adjoining can, the devices in connection with the operating of same being old and well known. Therefore I hereinafter describe my invention as though only one receptacle was in use, since the functions of the packing devices which I employ will be so described that their functions will be fully understood as being equally applicable for one or a series of cans.

In the accompanying sheets of drawings:- 7

Fig. 1 is an end elevation of sufficient of the framework of a type of carding machine to show the application thereto of my improved mechanism.

Fig. 2 is a plan of the parts shown by Fig. 1,

and in this figure two receptacles are shown and with a guiding member for directing the sliver hereto, firstly to one receptacle and then to the other receptacle in manner well known.

Fig. 3 is a similar end elevation to Fig. 1 but illustrates the driving and operating mechanism and means for putting same into and out of action for carrying out the packing of the slivers as is hereinafter explained.

Fig. 4 is an elevation of the parts shown by Fig. 3 and as seen looking from right to left of said figure.

Figs. 5 and 6 are drawings in detail illustrating the engaging and disengaging members for coupling the driving wheel to the cam shaft and for arresting said cam shaft as is hereinafter explained.

Figs. '7 and 8 are sectional side and end elevations of a part shown by Figs. 1', 3, 4 and 5 drawn to an enlarged scale.

A indicates the end frame of the machine, and B a receptacle into which the sliver is delivered.

According to the arrangementof devices shown by the drawings, the sliver 4a, as it is moved away from the machine, descends down the guiding member 2 so that it is carried between the lower and upper rollers 3 and 3a in order to move for ward through an opening in the base of the guiding spout or member a to descend in the direction indicated by the chainline 4a. into the receptacle B wheresuch sliver is packed by the member 5 descending into the receptacle B as it is moved vertically by the actions of the rotary operating cam 6a in well known manner.

The packing member 5 is adjustably fixed upon the vertical supporting members (he suspended by the bracket 6:1: which (when used with a plurality of" receptacles B, as shown by Fig. 2) reaches lengthwise the machine to have its outer ends fixed upon supporting bars 5. Each of these bars 6 has fixed to it brackets 6b and 60 which are pivoted upon the outer ends of the levers '7 and 7a respectively, so that said levers, by being arranged to oscillate about their supporting studs or pins '75 and 70, will carry the supporting rod and the packing member 5 in the desired vertical path.

The actions of the rotary cam 6a are transmitted to the levers '7 and 7a through the medium of the antifriction roller 7d which is mounted upon the lever '7.

The cam 6a is mounted upon its operating shaft 8, which shaft 8 extends horizontally from bearings A on the end frame A so that beyond said bearings A the cam 6a may be fixed upon said shaft 8 and in case two receptacles B are employed, as is shown by Fig. 2, the shaft 8 will extend lengthwise the machine so that another cam and a pair of levers '7, 711 may be mounted to operate the two devices for two difierent receptacles B as is well known. This shaft 8 extends through the end frame A as shown by Fig. 4 so that a chain or sprocket wheel 9 may be mounted to run loosely thereon, and through the hub 9a of this sprocket wheel an additional opening 9d of an appropriate concave formation to conform to a portion of the periphery of a partlycylindrical locking key 10, is made. The other portion which forms the partly cylindrical opening 90 made through a portion of the shaft 8 accommodates the partly-cylindrical portion of said shaft 8 which forms the key as is hereinafter described.

The sprocket wheel 9 is arranged to receive its motion by a chain 92) extending around it and forward over a sprocket wheel 3b fixed upon the shaft of the lower roller 3, a tension pulley 30 being employed to secure the constant tension of the chain 9b as is well known.

The shaft of the lower roller derives its motion in well known manner, and for the purpose of delivering the slivers as desired.

On the extending hub of the sprocket wheel 9 a pinion wheel 11 is fixed, and adjoining this pinion wheel 11 is a disc 11a, through which disc lie the outward end of the key 10 passes, and this part of the key which passes through the disc 11a is perfectly cylindrical to fit the cylindrical opening made therein. On the other side of the sprocket wheel 9 and mounted upon the same shaft 8 is a notched disc 12 which has a cylindrical opening made through it to receive and accommodate another cylindrical portion of the locking key 10 so that said locking key 10 is free to oscillate and is retained in its proper rotary position by its two outer ends, being of cylindrical formation, oscillating within the cylindrical openings in the disc 11a on one side and the notched disc 12 on the other side.

Fixed to, or formed integrally with theinner end of the key 10 is an engaging latch 13 which extends laterally from said key 10 so that a notch 13a therein will permit the engagement of a lateral arm 14 which reaches from its hub that is fixed upon the starting shaft 15 as is shown by Fig. 3.

The lateral arm 13 on the key 10 has also near its notched part 13a a shoulder 13b of a curved character that will permit it to slide freely over the outer end of the arm 14 during the rotations of the cam disc 12 in the direction indicated by the arrow at, 3. During such rotation or engagement of the arm 13 with the arm 14, the arm 13 is made to press a spring 13c so that during such compression the notched arm 13 is kept in engagement with the arm 14. However, when the arm 14 is moved 'by the oscillating of its shaft 15 by means of the handle 16 it is carried clear of the notched end 13a of the arm 13, then the spring 130 forces the arm 13 against the stop piece 1301 which is fixed upon the disc 11a.

I'he shaft 15 extends through its support 15a fixed to the framework A so that at its outer end a hand lever 16 may be fixed thereon, and this hand lever is arranged to be limited in its oscillatory movements by the projections 17a extending from a fixed bracket 17 in order that the handle 16 is prevented from being thoughtlessly moved too far beyond its desired path.

The cam 6a, as is hereinbefore described, is fixed upon the shaft 8 and has adjoining it (either fixed or formed integrally with it) a notched cam 6d, the notch 6) of which is for engagement with a weighted catch 20 which is pivoted on the end frame A of the machine.

The weighted arm 20a of the catch 20 is arranged so that it will normally keep the engaging end 20b of said catch in contact with the periphery of the notched disc 6d so that it will arrest same by engaging with the notch 6 thereon as is hereinafter explained.

Pivoted at 21c upon the face of the sprocket wheel 9 is a pawl 21 which en ages with the notch 12a formed upon the notched disc 12, while the spring 211) retains said pawl 21 normally against the periphery of the disc 12.

The actions of the several devices hereinbefore described are as follows:-

Assuming that the machine is in ordinary operation, but that the packing member 5 is in its raised stationary position, the said usual motions of the machine will continue by reason of the chain 9b continuing to rotate the sprocket wheel 9, since said wheel 9 will be revolving freely upon the shaft 8 without transmitting motion to any parts except, as may be desired, the retention of the receptacles B in rotary motion about their vertical axes, by reason of the train of gearing wheels 5 and s continuing their movements, being coupled to other devices in well known manner for securing the rotary motions of the receptaele B. At such time the starting handle 16 for the packing motion will be in its position which will carry the arm 14, which it operates, into the path of motion of the arm 13 fixed to the locking key 10, said position being shown by Fig. 3.

To start the packing member 5 into motion so as to carry out the packing operations, the handle 16 is moved so that by its shaft 15 it will move the retaining lever arm 14 out of engagement with the notched arm 13. Thus by the movement of the arm 14 out of said engagement it is carried by the handle 16 and retained out of the path of motion of the arm 13 as desired.

When the lever arm 14 is moved from contact-- ing with the lever arm 13 the spring 130 recoils, and by its recoil forces the lever arm 131) into engagement with the stop pin 13d which is fixed upon the disc 11a.

The movement of the lever arm 13 into contact with its stop pin 13d as stated, and as shown by Fig. 5, causes the key 10 to oscillate within the sleeve of the sprocket wheel 9 so that the edge of the key at 10a is brought into the concave hollow in the hub 9a of the wheel 9 and the wheel 11, and by the engaging of the edge 10a in the hub 9a the motions of the sprocket wheel 9 are transmitted to said shaft 8; thus these motions are made to 1 tion. Hence the relative positions of the end of the pawl 21, notch 12a and part 10a of the key 10, are always retained as described during the rotary motions of the shaft 8.

It will be observed that the hand lever 16 may be operated at any time by the attendant, but

when such hand lever 16 has been operated by the attendant as stated, unless the notch 9d registers with the cut-away part of the key 10, said key 10 is prevented from being oscillated by the spring 130.

This prevention of the oscillation of the key by the spring 130 remains active upon said key 10 until, by the sprocket wheel 9 carrying the concave hollow 9d into the registered position shown in dotted lines Fig. 5, said spring will move the arm 13 until it reaches the stop piece 13d, at which time the key 10 will have oscillated in the partly cylindrical part of the shaft 8 and the hollow cavity 951 in the hub or sleeve 01' the wheel 9 as is hereinbefore explained.

The pawl 21 which is pivoted upon the sprocket wheel 9 as before stated, and therefore rotates with said sprocket wheel, is arranged to fall or descend under the actions of its spring 211) into engagement with the notch 12a on the disc 12 as is shown by Fig. 3 simultaneously with the registering of the hollow part 9d in the hub of the wheel 9 and the partly cylindrical part in the shaft 8 within which the key 10 is situated. Thus at all times the starting into action of the cam 6a. which operates the packing member 5 and the arresting of said cam by the actions of the weighted engaging pawl with the notch 63 on the disc 6d, will coincide, so that the starting and stopping of the actions of the packing member 5 are always effected relative to the rotary motions of the shaft 8 irrespective of any movements that the attendant may transmit to the handle 16 of the stopping and starting devices described.

it will be further observed that when the packing member 5 is arrested it is desirable that it should be arrested in its highest position as shown by l, and such a position of rest is secured by the adjustment or" the operating parts for stopping and starting the shaft 8 into motion.

Further than this it will also be observed that the notched disc and its notch 61 are arranged to engage with the end 29b of the weighted catch 20 at each revolution of the shaft 8, and that the disengagement of the driving means to the shaft 8 is effected when the cam 6a is approaching its highest position on moving in the direction indicated by the arrow 11:, Fig. 3, so that by such disengaging taking place in this position the weight of the packing member 5, and the operating devices which move it under its weight, will press upon said cam 6a to one side of its axis of rotation so that the tendency of said weight is to cause the cam 6a to be reversed in its direction as compared with the direction indicated by the arrow CC, so that on such occasion the notch 6 of the disc Set is brought into contact with the catch 20 as described, where it will be efiectively secured against further movement, and by reason of the position of the cam 6a any forward motion is also prevented. Therefore the packing memher 5 is retained in its raised position permanently when stationary.
